From a messy cart to maximum savings in 4 simple steps.
Shop on Amazon.in as you normally would. Add everything you want to buy into your single cart without worrying about minimum spend limits or bank offer rules.
Open the PromoSplit extension on the Cart page. It will rapidly scan your items in the background, extracting every live bank discount and EMI offer available.
PromoSplit presents a clean checklist of all the banks and payment methods it found. Just tick the ones you actually own (e.g., SBI Credit Card, Amazon Pay UPI).
The AI reveals your optimized Dashboard. Click "Clear Basket", then "Create Basket for Order 1" to instantly load the exact items needed to max out your first card. Repeat for Order 2!
We designed PromoSplit so that anyone—even a 6-year-old or a grandparent—can use it.
And counting! The more you shop, the more you save.
PromoSplit uses Artificial Intelligence to read the complex, messy offer details on Amazon. Just like you can ask different people for advice, you can choose which AI "brain" you want to use!
In the extension, you'll see a simple dropdown menu. You can pick Google Gemini or OpenAI (GPT). If one AI seems to be missing an offer, you can simply switch to the other one and try again!
Amazon shows hundreds of offers, but you probably don't have every credit card in the world! After the AI scans your cart, it makes a simple checklist of the banks it found (like SBI, HDFC, or ICICI).
All you have to do is tick the checkboxes for the cards you actually have in your wallet. The extension will automatically ignore the offers you can't use.
What if Amazon has a "Max ₹1500 discount per card", but you and your spouse both have an SBI card?
No problem! Next to every offer, there is a small "Claims" box. Just change the number from 1 to 2. The AI will instantly realize it can split your big cart into two separate orders, using both of your cards to get double the discount!
Once you click "Optimize", the magic happens. You'll see a beautiful Dashboard showing you exactly how to split your cart into "Order 1", "Order 2", etc.
It's incredibly easy to checkout: Click "Clear Basket" to empty your current messy cart. Then, click "Create Basket for Order 1". The extension will automatically visit the product pages and add the exact right quantities to your cart for you. Pay, and repeat!
